Abstract
An endoscope apparatus includes an imaging element, a flexible substrate, and a flexible heat release sheet. The imaging element is built in an endoscope front end portion so as to receive incident light from a subject. The imaging element and components of a circuit for driving the imaging element are mounted on the flexible substrate and the flexible substrate is built in the endoscope front end portion. The flexible heat release sheet includes a first region attached to a given region of the imaging element other than a light receiving surface of the imaging element and a second region thermally contacted to a heat release member disposed in the endoscope front end portion.
